you've got democratic senator mark udall now calling for john brennan's resignation. also got senator martin hinrich, also a democrat in the senate intelligence committee. you've got another democrat, oregon senator ron wyden calling for potential criminal charges filed against whoever it was in the cia who spied on the senate. >> if a 19-year-old hacker searched senate files this way, that hacker would be sitting in jail right now. i want a public accounting at this point. i want to know who authorized this act. i want to know why they thought it was legal, and i want to know who is going to be legally held responsible. >> and now tonight, the first republican senator to all for brennan's resignation has emerged, not surprisingly, it is senator rand paul. president today said he has, quote, full confidence in john brennan as director of the cia, even as he went on to talk about the poor judgment the cia showed when it decided it was a good idea to spy on congress. joining us, siobhan gorman, the intelligence correspondent at "the wall street journal." thanks for joining us tonight.
